LEATHER POLISH.

Ho Drawing.

To all whom it may concern:

. application, a brilliant and lasting gloss to shoes and other leatherobjects. Another object of the invention is to pro-l vide a polishingcomposition of the above described character in a convenient shape forits direct application to the leather, the elongate, cylindrical formcommonly recognized by the name stick being best adapted for thepurpose.

The stick of polish made approximately of the proportions of the wellknown sticks of shaving soap, may be wrapped in tinfoil or otherprotective covering but it is preferably enclosed in a casing providedwith a means for its gradual protrusion.

In using the device, the stick is projected from the casing and itsprotruding end is rubbed upon theleather. The polish thus deposited in athin layer of substantially uniform thickness, is subsequently rubbed toa gloss by means of a brush or cloth with more ease than in the use ofliquids or pastes since the manner of application prevents the depositof more polish than is needed to produce the desired gloss and insuresits even distribution over the entire surface of the leather. a

The composition consists of a solid or semi-solid hydrocarbon, such asparafiin or tallow, which serves to provide a waterproof coating, afatty substance, such as linseed oil which acts as a preservative andaids in the production of a mass of the desired consistency, acommercial base in solution, as for example, a solution of sodiumhydroxide which neutralizes any acid or lime that may be presenttherein, a hard wax, preferably carnauba wax, water, and a dye materialof the required color.

The following compositionof the materials in the given proportions hasbeen found Application filed July 27,

1923. serial No. 654,153.

most suitable in the production of a .black leather polish of therequired consistency:

Paraflin,20 grams.

Linseed oil, 5 cubic centimeters.

A 25% solution of sodium h droxide (NaOH) or sodium carbonate (Na O .05cubic centimeter.

Carnauba Wax, 20 grams.

Nigrosine (oil-soluble), .05 gram.

Water, 250 cubic centimeters.

Nigrosine (water-soluble), .04 gram.

The mixture is produced by warming the parafiin to 100 (J- preferably ina water bath, then adding thereto the sodium solution and continuingheating until a smooth homogeneous mass is obtained. The carnauba wax isthen added and the boilingcontinued until'the mixture is thoroughlysaponified. At this point of the process, the oil-soluble nigrosine ismixed with the other ingredients by stirring and 250 cubic centimetersof water is added in small quantities. Finally the water-solublenigrosine is dissolved in the remainder of the water and added to themixture.

The composition thus prepared is placed in molds of the desired size andform and solidified by cooling. The sticks of the composite material areplaced in suitable holders, such as that shown in the drawin andthe-composition is applied to the leat er to be polished, by gentlyrubbing an end of the stick over the surface thereof.

The composition may be made for use of differently colored leather bysubstituting a dye of the desired color for the nigrosine. For example:creolin yellow or creolin orange, either separate or mixed together, is

suitable in preparing the composition for use on tan or yellow leather;creolin brown either separately or mixed with creolin 0range, for brownleather, -and scarlet creolin red for ox-blood leather. All these dyesare oil-soluble and are added to the mixture after having been dissolvedin linseed oil.

The water-soluble nigrosine is used mere ly to give color to the waterrequired in the a composition and thereby -add to-the staining qualityof the composition, and it may be omitted if the ingredient is notreadily available.

Water may be omitted from the composition by reducing the quantity ofthe carnauba Wax but the use of Water is preferable since it provides asolvent for parts of the solid or semi-solid ingredients not dissolvedin the oil, and. since it promotes saponification and renders the massmore homogeneous.

What I claim ters Patent is:

1. A composition of matter adapted to form a semi-solid leather. polishcomprising paraflin, linseed-oil, a, solution of sodium gydroxide,carnauba wax and an oil-soluble 2. A composition of matter adapted toform a semi-solid leather polish comprising paraffin, linseed-oil, asodium hydroxide solution, carnauba wax, an oil-soluble dye,

water and a water-soluble dye.

3'. A composition of matter adapted to form a semi-solid leather polishconsisting of paraflin 20 grams, linseed-oil 5 cubic cenanddesire tosecure by Lettimeters, a twenty-five per cent sodium hydroxide solution.05 cubic centimeter, carnuuba wax, 20 grams, and an oil-soluble'dye.

4. A composition of matter adapted to mm a semi-solid leather polishconsisting,

of puruflin 20 grams, linseed-oil 5 cubic cen-- timel'ers, a twenty-fiveper cent sodium hydroxide solution .05 cubic centimeter, 'carnauba wax20 grams, an oil-soluble dye, and water 250 cubic centimeters. 5. Acomposition ofinatter adapted to form a semi-solid leather polishconsisting of paraffin 20 grams, linseed oil 5 cubic centimeters, atwenty-five per cent sodium hydroxide solution .05 cubic centimeter,carnauba wax 20 grams, an oil-soluble dye, water 250 cubic centimeters,and-.1 Watersoluble dye.

In testimony whereof I have afiixed my signature.
